In the automated manufacture of magnetic recording heads, an electrically conductive path between the head's magnetic ferrite members and a ground plane is established by automatically delivering a small, low-melting pellet of an electrically conductive material to a location adjacent the ferrite member and a ground plane member, and then subjecting the pellet to heat. It is necessary to provide an electrically conductive path, or joint, between a magnetic head's core and its adjoining metal mounting platform. This path acts as a static-charge bleed-off path from the head to the platform or ground plane. In an automated process, the head's core legs are automatically inserted through holes in the metal platform. A solid pellet of a composite material (for example, a low temperature melting wax, plastic, epoxy resin, etc.
